I have had the Purezone Halo True Hepa Air filter for a few months now. I suffer from terrible indoor/outdoor allergies and I keep this in my bedroom. I feel it has made quite a difference with my breathing as well, as I also deal with asthma relating to my allergies acting up. I love that there is a nightlight, timer, fan and speed setting. It is easy to use.  I would highly reccomend this Air purifier to any allergy suffering people like myself.
